HOSE- LEAK STOP OR JACKET.

SPECIFICATIONformng part of Letters Patent No. 534,280, dated February 19, 1895.

Application led August 16, 1894. Serial No. 520,538. (No model.)

T0 a/ZZ whom t may concern:

Be it known that I, AUGUSTUS G. PARK- HURs'r, of the city of Minneapolis, county of Hennepin, and Stateyof Minnesota, have invented a certain new and Improved Hose- Leak Stop or Jacket, of which the following is a specification.

My invention relates to improvements in devices for stopping a leak in any hose, and the particular object I have in view is to provide a simple and inexpensive device which can be quickly applied to a fire hose, and which will effectually stop any leak therein.

It very frequently happens at a tire that the pressure of the water will burst the hose and render an engine to which it is attached useless until a new hose is brought and substituted for theleaky one, and much valuable time is lost which might be saved by having' an attachment at hand for stopping the leak.

My invention consists 0enerally in two sleeves or jackets slidably arranged in a frame work and adapted to` receive a hose, and means for bringing the inner ends ofthe two sleeves together and holding them in that p0- sition and stopping the leak in the hose, all as hereinafter described and particularly pointed out inthe claims.

In the drawings forming part of this speci.

fication; Figure 1 is a plan view of inyinvention attached to a hose. Fig. 2 is a side elevation of the same. Fig. 3 is a longitudinal and vertical section of Fig. 2. Fig. et is a plan view, the sleeves being disconnected and the hinged upper half of one being thrown back.

In the drawings, 2 represents suitable standards for supporting the parallel bars 3 arranged thereon. ably single iron bands having a depressed middle portion and downwardly turned ends forming the legs of the standards. The parallel bars 3 are rabbeted upon their inner upper edges, and metal strips .tare arranged over these rabbeted edges, thereby forming a groove in the upper inner edges of the parallel bars. The parallel bars are preferably made thicker in the middle than at the ends for the purpose hereinafter described. Arranged on the bars at either side of the middle thereof are the sleeves or jackets 5 and 5. Each sleeve is halved longitudinally, and the upper half of each sleeve is connected by hinges 6 on one The standards-2 are preferside tothe lower half and is adapted to swing `back to allow a hose to be placed in the lower half. Each upper half is provided with suitable springs 7 adapted to engage catches 8 provided on each lower half, by which the upper halves will be firmly secured when itis desired to mend aleak in the hose. Thelower half of each sleeve is provided with longitudinal ribs or feathers which are adapted to fit into and slide in the grooves in the parallel bars, as indicated by dotted lines in Fig. 1. Each lower half is also provided with outwardly extending lugs 9. The inner ends of the sleeves are beveled thereby forming a comparatively tight joint when brought together, and the upper and lower half of one sleeve is provided with suitable spring catches lO adapted to engage notches or slots in the end of the opposite sleeve, as shown in Fig. 3. The sleeves 5 and 5 are each provided at their outer ends with thel inwardly turned edges or flanges 9 and gaskets or rings 10 are arranged in the outer ends of each of the sleeves and are prevented from sliding out the ends thereof by the flanges 9. The gaskets 10 form a tight joint with the hose and prevent water from leaking out around the ends of the sleeve. Passing through the thickened portions of the bars 3 and journaled'in bearing therein, is a shaft 11. The shaft 11 is provided with cranks 12 varranged on opposite ends thereof and with pulleys 13 arranged one at each end of said shaft and extending up through slots 14 inthe bars 3. The shaft 1l is also provided with a ratchet wheel 15 riphery of said pulleys 13 and the other end thereof secured respectively to the lugs 9 on the lower half of the sleeve 5. Chains 18 are also provided each having one end secured to the periphery of the pulleys 13 on the opposite side of the pulley from the ends of the chains 17. The chains 18 pass over idler pul- 'leys 19 arranged in vertical slots in the bars 3 and journaled therein, and are secured respectively to the lugs 9 on the lower half of the sleeve 5. v t

The operation of the device is as follows: When a hose springs a leak the hinged por- ICO tions of the sleeve are thrown back and the hose laid in the lower halves of the two slee ves. The upper or hinged portion is then shut down over the hose and fastened by the catches 7 and S. Then by turning the cranks 12 the sleeves will be drawn together, the beveled edges telescoping each other until the catches engage the slots in the sleeve 5. The sleeves will then be firmly clamped to- Io gether and a practically water tight jacket will be formed around the leak in the hose and will render the hose as serviceable as a new one and with a greatsaving of time.

Having thus described myinvention, I,

15 claim as new and desire to secure by Letters Patent y i 1. The combination, with a suitable support, of longitudinally divided sleeves arranged thereon, the upper portions thereof :zo` being hinged to the lower portions, said lower portions being adapted to receive a hose, means for securing the detached side of said upper portion to the detached side of said lower portion, andmeans for bringing the 'ad- 2 5 jacent ends of said sleeves together, and making a water tight joint between the ends of said sleeves substantially as described.

2. The combination, with a suitable support, consisting of two parallel bars nionted upon suitable standards,of longitudinally divided sleeves arranged to slide thereon, theV upper portions of said sleeves being hinged to the lower portions, and said lower portions being adapted to receive a hose, gaskets arranged on the inside of said sleeves at the outer ends thereof, the inner ends of said sleeves being beveled, and means for bringing the adjacent ends of said sleeves together, substantially as described.

3. The combination, with a suitable support, of longitudinally divided sleeves slidably arranged thereon, the upper portions of said sleeves being hinged to the lower portions, said sleeve portions being adapted to receive a hose, a shaft mountedin bearings between said sleeves and carrying pulleys, chains connecting `said sleeves, and pulleys wlierebywhen the shaft is tiir'ned the sleeves will be drawn together, substantially as described.

In testimony whereof I have hereunto sot my hand this lothday ot July, D. 1894.
